Felt Ball Rugs are made entirely of felted wool. Wool, which is a basic raw material used to manufacture this type of rugs (carpets) is called Lamb’s wool which is imported from New Zealand. The quality (softness or fiber size) used in most of the rugs is 29 microns. Sometimes, Merino Wool of 19 microns which is much softer than Lamb’s wool and expensive (up to 3 times) is used in place of this wool. The wool that is in its primary raw state is then processed through carding and dyeing. The dyeing technique used is Swiss (Azo-free dyeing). Wool hence colored in the desired tone is then felted to balls and used for making rugs.
